In the production of aluminum beverage cans, the Ball Corporation sprays an epoxy coating inside the cans before they are filled. A coat of epoxy builds up over time on a ventilation manifold and the nozzle tip used to spray the cans. Our team has created an automated two-part cleaning system using compressed air and a linear scraper to remove epoxy from these components. Our system drops the cleaning time and machine downtime from twenty minutes to five minutes per machine per day.

During the production of aluminum beverage cans, the interior surface is sprayed with a liquid coating that forms a barrier between the metal and the drink. Over time, this coating accumulates on the spray nozzle tip, compromising coating quality and increasing production costs due to manual removal. We have created an automated solution to efficiently and effectively clean coating buildup.

Left Ventricular Assist Devices (LVADs) are used for the treatment of heart failure. However, all current devices require an external power source with energy supplied by a percutaneous driveline. Excessive mobility of the driveline delays healing and incorporation of the driveline in the subcutaneous tunnel. For this project, Team 13 developed an improved method to secure an LVAD driveline.
